Each student chose a scientific question to research and explore.
"My question is 'which metal is most resistant to corrosion'," explained Amber Conaway.
Amber used 3 types of metal, copper, aluminum and zinc-coated steel, immersing them in tap water, salt water and bleach for 2 weeks and the result?
"Zinc-coated steel is the most resistant to corrosion."
The fair offers students an opportunity to compete for awards including college scholarships.
"At least 2 students each year receive full scholarships to Temple University," said Carver committee member Claudia Tucker-Keto. "Sometimes it's partial scholarships; sometimes it's something that can actually help them out to continue to foster their scientific exploration."
7th grader, Alexandra Sicees is among the youngest students participating in the fair. Her scientific question asks 'does the angle and number of blades affect the speed of a windmill?'
"Scientists say 3 blades are more effective on windmills but I found that 6 blades were more effective in my project," she answered.
One of the judges explained what they look for in the projects.
"What we're looking for, students who show interest really enjoy scientists who show that what they've done has been worth their time," said James Jetter.
The top 3 winners from grades 7 through 12 in each category will receive the prestigious George Washington Carver Science Medal. Those students will then go on to represent the city in the Delaware Valley Science Fair in early April.
